1. Turn the pump off and close the proper valves to isolate the filter system. For most portable spas, closing the valve is not necessary. Just make sure the breaker is at least turned off.
2. Remove the filter element or cartridge and spray it off thoroughly with a high-pressure hose nozzle.
3. Reinstall cleaned filter element or exchange filter element with a clean stand by one if available. As filter elements become increasingly dirty, occasionally soak then in a filter cleanse solution, then spray off element thoroughly before placing back into filter canister.
   If your filter has a lid, check to make sure the gasket or o-ring is properly seated in place.
4. Open necessary valves and/or turn system back on.
5. Carefully open air bleeder valve to release any left over air from filter canister until water comes out.
6. Check for any leaks.

1. Turn on the hydrotherapy jets to assure accurate water readings.


2. Test for TOTAL ALKALINITY.
   The proper range for Total Alkalinity should be 80 to 120 PPM.
   If the Alkalinity is Low, add Sodium Bicarbonate or Baking Soda to raise the Alkalinity.
   See Table A.
   If the Alkalinity is High, add Sodium Bisulfate or Dry Acid to lower the Alkalinity.
   See Table B.


3. Test for pH.
   The proper range for pH is between 7.4 to 7.6.
   If the pH is below 7.4, add ph Increaser, Sodium Carbonate or Soda Ash.
   To determine how much to add, use the “base demand” test and refer to Table C.
   If the pH is above 7.6, add pH Down, Sodium Bisulfate or Dry Acid.
   To determine how much to acid to add, use the “acid demand” test and refer to Table D.


4. Test for CALCIUM HARDNESS.
   The proper range for Calcium Hardness should be 200 to 400 PPM.
   Add Calcium Hardness Increaser (Calcium Chloride) to raise the Calcium Hardness.
   See Table E. To lower Calcium Hardness, add water from a softer source or drain spa and refill with fresh water.


5. Test for BROMINE RESIDUAL.
   The proper Bromine residual should be in the range of 1.0 to 3.0 PPM.
   Fill your floating dispenser with bromine tabs (approx 3-5 tablets) if low or if empty.
   Adjust the dispenser opening for necessary increase or decrease of bromine residual.
   If your spa is set up with an inline bromine feeder, turn spa system off, remove lid, add tablets and adjust control setting if necessary. Secure lid and oring and turn system back on. Check for leaks.


6. SHOCK TREATMENT.
   Weekly OR if the Bromine level is low, AND/OR if cloudy, smelly water exists.
   Shock the water with a Non-Chlorine Shock (Potassium Monopersulfate) at 2oz. Per 500 gallons.

CHANGING SPA WATER

Hot tub/spa water should be changed once or twice a year, depending upon usage. To do this, drain the spa and clean the side and bottoms, etc. Baking Soda acts as a great natural abrasive cleaner or TLC, a more heavy-duty mild acid cleaner, can be used to help remove grime and mineral scale. Refill spa with fresh water, start up spa system and balance water chemistry as necessary.
